BOLT ANI) SOCKET CONSTRUCTION.

Application led January 28, 1922. Serial No. 532,445.

To all whom it may concern.'

Be it known that I, ENOOH OHNs'rRAND, a citizen of the United States of America, and resident of Mohawk, in the county of Herkimer and State of New York, have invented new and useful Improvements in Bolt and Socket Construction, of which the following is a specification.

This invention relates to bolt and socket construction of the type used for fastening doors and is particularly adapted for use in fire-resisting cabinets such as vaults, safes, filing cabinets, etc., which have a metal lining or facing, usually sheet metal.

The usual construction of fire-resistant receptacles provides slidable locking bolts on the door operating through openings in the metal facing of the door and into similar openings in the metal facing of the door casing.` These openings are frequently not reinforced but are merely holes in the metal facing and as such are subjected to pulling or drawing of the metal when the door is under strain from heat, thereby setting up play between the door and the door casing and permitting the door to open more or less and expose the contents of the cabinet. Moreover, these openings whether reinforced or not soon become worn through the cutting action of steel on steel land fail to produce a tight fit for the door. In addition these openings often become corroded due tothe action of moisture, so that the bolt does not slide easily. Gritty particles of the heat insulating material between the walls ofsuch cabinets can usually fall directly upon the metal surfaces defining the opening and greatly accelerate the wear thereof.

Objects of the invention are to produce a bolt and socket construction which will indefinitely maintain a tight fit for a door, to strengthen the guide or socket openings for the bolts, toeliminate corrosion and wear of the guide openings, to provide for smooth and easy operation of the bolts, and ingeneral to improve devices of this kind.

The invention comprises guide members attached to the door and door casing adjacent to and in alignment with the openings therein for the bolts. Each of these guide members preferably comprises a tubular jacket and a bushing therefor. The jacket is preferably of a hard metal auch as steel, and

the bushing of a softer metal such as bronze.

VThe outer portions of the bushing are suitfacing adjacent the opening is suitably de-l pressed so that the riveting flange of the bushing will be flush with the plane of the facing. The guide members received in the door casing are in the form of sockets having closed inner ends. The closed end is preferably formed by providing these members with bushings in the form of thimbles.

In order to illustrate the invention one concrete embodiment thereof is shown in the accompanying drawings, in which- Fig. l is a front elevation;

Fig. 2 is a section on greatly enlarged scale on the line 2 2 of Fig. l;

Fig. 3 is a still further enlarged section of the bolt guide member shown at the left side of Fig. 2;

Fig. 4 is a sectional view of a modified guide member similar to that shown in Fig. 3; and

Fig. 5 is an enlarged section of the bolt guide member shown at the right of Fig. 2.

The invention is shown as incorporated in a safe A of usual form having double doors B and C supported on the safe by hinges D, a lock dial E, and anactuating handle F for operating bolts 6 by means of a series of rods 7 and bell cranks 8 as shown in dotted lines in Fig. l. The safe has the usual outer oasing 9, inner casing or lining 10 and heat insulating material l1 in the .space between the inner and outer casings as indicated in Fig. 2. Y

The ldetails of the particular bolt and socket construction chosen to illustrate the invention are shown' in detail in Figs. 2, 3, 4 and 5, and will now be described. Since the bolts and guide members therefor are all similar inform and construction, descrip-v tion of one assembly thereof will be sufficient. Referring now to Fig. 2 wherein a portion of door Band the adjacentportion of safe A comprising the door frame are shown, the inner, casing 10 ofboth door.

and door frame are provided With .aligned openings 12 and 13 respectively etv in which are made fast guide members 14 and 15 extending respectively Within the door and Within the safe Wall. These guide members reinforce the openings 12 and 13. Member 14 comprises a jacket 16 of hard metal as steel, provided With a bushing 17 of softer metal such as bronze. The bronze bushing 17 is bent or swedged outwardly at its ends forming flanges 18 and 19. The bushing 17 extends through opening 12 so that ange 19 Contacts the outer face of inner casing 10 ofthe door thereby riveting the guide member 14 securely in place and pressing jacket 16 into intimate contact with the inner facce kof casing 10. This casing adjacent the openinglQ is inwardly depressed as indicated at 20 so that flange 19 is iiush with I? the lane of the outer surface of casino 10.

In Fig. 4 is shown an alternative structure for thel guide member on the door which comprises a steel jacket 16a having an inwardly projecting flange 16b which serves as an abutmenty or stop for the inner end of bushing 173, and an outwardly extending flange 16 providing a greater area of contact with the innerv face of casing 10 adjacent its inward-ly bent portion 20. This form of gu-ide member is held in place by the outer flange 19El upon the bushing 17a but the bushing is held in its jacket 161L only by friction produced by its tight fit within the jacket and not by an inner flange as shown in Fig. 3.

Bushing 17 in guide member 15 (Fig. 5) is in the form of a thimble having a closed inner end 21 preferably integral With the bushing 17 and having a circumferential fiange 22 enclosing the inner end of jacket 16 in the manner of flange 18 on bushing 17. Guide member'l is held in place by a riveting flange 19 lon bushing'17 received in the depressed portionQO of casing 10 in the manner previously described. The provision of the closed inner end for guide memberv 15 prevents the access; of gritty particles of the heat( insulating filling 11 which would produce Wear on the bearing surface of the bushing.

The socket arrangement herein disclosed provides a strong reinforcement for the openings 12'and 13 in the inner casings 10 obviating all drawing of the metal when the doors B and C expand froml the heat as in the case of lire. The bronze bushings 17 and' 17 in guide members 14 and 15 which do not cor'rode insure easy and smooth operation of bolts 6 Without appreciable Wear for an indefinite period. This absenceof Wear, dueto the provision of the' bushings of softer metal than the bolt and to the exclusion ofgrit fr'oin the interior r`of the cassocket' member' 15' produces a permanently tight fit for the doors of the safe, thus insuring complete protection to the contents in the event of fire.
